ECOLOGICAL RISK ASSESSMENT IN THE REGULATED WATERCOURSES

Journal of Ecological Engineering, 2015
Ecological risk has not been identified well enough for the designers and contractors to take any actions for its limitation. It results from the lack of the basis formed to assess its level objectively. The aim of this study was to determine the standards useful in the evaluation of the ecological risk for aquatic plants in rivers, where it is planned

Engineering Microbial Particles for Next‐Generation Biomedical Platforms

Advanced Science, EarlyView.
Microbe‐derived particles (MDPs), which include extracellular vesicles, outer membrane vesicles, inclusion bodies, polysaccharide particles, and virus‐like particles, represent a rapidly expanding category of bioinspired nanomaterials. With their natural origin, intrinsic biocompatibility, and highly programmable functionality, MDPs serve as a ...

Neglect of Temperature and pH Impact Leads to Underestimation of Seasonal Ecological Risk of Ammonia in Chinese Surface Freshwaters

Journal of Chemistry, 2019
Ammonia nitrogen (AN) is evaluated with fixed water quality standards (WQSs) in aquatic environment management in China. Since the toxicity of AN can be influenced by water parameters, the current evaluation is not rigorous and may result in problematic ...

Comparative Study on the Characteristics of Bacterial and Microeukaryotic Communities in Aquaponics and Recirculating Aquaculture Systems [PDF]

Progress in Fishery Sciences
The aquaponics system, an integrated ecological agriculture model, effectively combines aquaculture and the cultivation of aquatic plants. This system not only utilizes the nutrients in aquaculture water to promote plant growth but also purifies water ...

Extra Climate Benefits From Afforestation Due to Reduced Forest Fragmentation in China

Advanced Science, EarlyView.
Afforestation in China reduced forest fragmentation in 2015, transforming 51.8 M ha of edge forests into interior forests. This enhanced carbon sequestration (1.4±0.2 Pg CO2e, a cooling biogeochemical effect), while reduced albedo (−0.9 Pg CO2e, a warming biophysical effect) partially offset the gain, yielding a net extra climate benefit of ...

Resistant Peanut Genotype Reprograms Rhizosphere Metabolism to Enhance Bacterial Wilt Suppression

Advanced Science, EarlyView.
The resistant peanut genotype selectively recruits beneficial bacteria, which coincides with the activation of salicylic acid (SA)‐dependent systemic acquired resistance (SAR) against Ralstonia solanacearum. Keystone rhizosphere metabolites are positively correlated with both beneficial microbiome assembly and SAR gene expression.

Ecological risk assessment of endocrine disruptors.

Environmental Health Perspectives, 2000
The European Centre for Ecotoxicology and Toxicology of Chemicals proposes a tiered approach for the ecological risk assessment of endocrine disruptors, integrating exposure and hazard (effects) characterization. Exposure assessment for endocrine disruptors should direct specific tests for wildlife species, placing hazard data into a risk assessment ...
